DESCRIPTION
The SA638 is an IF receiver chip which serves the dual mode
functionality required by the IS–54 standards for North American
cellular telephones. It provides for both the analog FM (AMPS
mode) and DQPSK (TDMA digital mode) IF receive functions in a
monolithic BiCMOS Integrated Circuit housed in a compact
SSOP–24 plastic package.
